INTRODUCTION In April 1992, PULSE-EM survey, was carried out on a property owned by GRANGES INC., CHAZEL Project, in Chazel Township, province of Quebec.

The PULSE-EM surface (DEEPEM) survey was carried out on Chazel Project to locate the presence of sulfide-rich conductive horizons at depth.

PROPERTY, LOCATION AND ACCESS The Chazel Project is located approximately 20 kms North-East of the town of La Sarre, Chazel Township, (range VII lot 6-7, range VIII lot 1 to 6), province of Quebec.

The property is easily accessible by the range 8 and 9 road which can be taken from the road La Sarre Beaucanton.

The property claims have been registered with the Quebec Department of Natural Resources and their numbers are presented on figure #1 of this report.

GEOPHYSICAL SURVEYS From April 15 to 21, 1992, a total of 12.0 kms was covered by the PULSE-EM (DEEPEM) survey.

The equipment used was a PULSE-EM system manufactured by Crone Geophysics, consisting of a 20-channel digital receiver and a 2-kw (20A) transmitter. ~ -2-

SURVEY SPECIFICATIONS The PULSE-EM system consists mainly of two components. The transmitter, powered by a 2000W gas generator, produces a rectangular wave with a linear ramp cut-off. This signal is circulated in a single-turn loop of electric wire laid out on the ground and whose dimensions are dictated by the conductivity of the surrounding medium and by the required depth penetration. A total of two transmitting loop positions were alternatively used with dimensions of 500m x 500m with 5.5 amperes for #2 loop and 500m x 700m with 4.5 amperes for #3 loop.

The sudden cut-off of the current in the transmitting loop (typically 5 to 10 Amperes) causes the induction of secondary currents in any conductive structure that is ® located within the activation distance of the loop.

The second component of the system, the receiver, detects the variation of the magnetic field associated with these secondary currents. A sensor picks-up the signal at surface and the receiver measures the amplitude of the various time-windows (16 channels) of the decaying secondary magnetic field. The decay rate, the amplitude of the individual windows (channels), and the spatial variations of these features are all specific characteristics of the target.

Measurements for each loop position were taken every 50 metres along the survey lines. The decaying secondary magnetic field is measured in two components: the vertical. component (Z) and the horizontal component (X) which is parallel to the survey line. The results are presented in • the form of profiles of the amplitude of the individual channels, plotted against the reading point. -3-

RESULTS AND INTERPRETATION The Deepem profiles are generally fairly quiet. The only significant event occurs at about 200N between lines 3000E and 3400E. This weak response shows up as a positive peak on the early channels of the Z component and as a weak - to + crossover on the X component.

Such a response can only be attributed to a sudden change of resistivity, going from higher resistivity South of the peak, to lower resistivity North of the peak and it is most likely related to a step in the bedrock surface. There is probably little overburden (<1Om-2Om) at about 100N-200N South of the "break" and the overburden cover (probably clay material, which is an electrolytic conductor) suddenly increases at 250N (>2Om-40m).

A fault or a shear zone is the most likely cause for this phenomenon. As for semi-massive or massive metallic conductors, we do not believe that there are any within the first 15Om, which is the approximate search capability of the DEEPEM system in such an environment. -4-

CONCLUSION AND RECOMMENDATIONS The DEEPEM survey which has recently been completed on the Chazel claim group has failed to map any metallic conductors within the first 150m. Only a fault or similar structure was outlined.

If such a fault is believed to offer some potential for gold mineralization, then it should be further investigated with a short drill hole.

Otherwise if the target is metallic sulphides, then Induced Polarization might help in tracing such mineralization. The overburden cover, which appears to be • fairly conductive, may act as a mask and will certainly reduce the search capability of the I.P. method, so large dipoles (50m or more) should be used.
